jquery - back to top

Question

I see this fiddle sample here

I want when "to the top" appear, an click! should scroll to the top smoothly or slow

$(window).scroll(function() {     if ($(this).scrollTop()) {         $('#toTop').fadeIn();     } else {         $('#toTop').fadeOut();     } }); 

Answer 1

$("#toTop").click(function () {    //1 second of animation time    //html works for FFX but not Chrome    //body works for Chrome but not FFX    //This strange selector seems to work universally    $("html, body").animate({scrollTop: 0}, 1000); });
